The Gunners suffered a 2-0 defeat at Chelsea on Sunday.
Wenger said: “Our average age is 23 years and Chelsea’s is 29 – I think that it showed in the decisive moments on the pitch.
“I think we were a bit naive on the first corner and then we got caught on the break.
“We have to give everything until the last second of the championship, whatever happens.
“We can’t have any regrets, and if Chelsea are better than us and win the title, or if it’s Manchester United, then we will congratulate them along with everyone else.
“But that’s not a reason for us to give up.
“We have to show the dignity of our ambitions and sometimes that means fighting until the end.”
Arsenal face Liverpool at the Emirates on Wednesday.
